Total nonsense about Prague. There are 2 great techno clubs/bars on each Žižkov, Vršovice or Holešovice street, lol. It's mostly locals and expats listening to guys doing it for fun with no managers or marketing (or entrance fees), so yeah it makes sense you have no idea if you don't live there, but just walk around the city and listen.
Let me get you a list for your next Prague trip: Fuchs 2, Bike Jesus, Altenburg, Bukanýr, Ankali, Roxy, Onyx, Jilská 22, Swim, Centrála, Cross, Storm, Chapeau Rouge, Planeta Za, Wildt, Mecca, Studio ... That's just the very well known ones, then you have hundreds of random small unknown places with great unknown DJs all around the city, and many great rave events in places like nuclear bunkers, castles, churches, forests.
The mainstream event halls normally used for big artist concerts are now hosting raves too.
